The problems have begun before a regular-season pitch has been thrown.

Aaron Hicks will begin this Yankees season on the injured list. The outfielder with a balky lower back got a second cortisone shot Sunday, another injury issue for a team already down ace Luis Severino.

It is unclear how much time Hicks will miss, but ESPN reported he will not play during the opening series against the Orioles, which begins March 28.

Aaron Boone conceded Saturday there was a chance Hicks, who recently signed a seven-year, $70 million extension, would not be ready in time.

“We are getting close to that point where it is cutting it real close,” Boone said. “I feel pretty good about the fact that he will probably be ready by Opening Day but there is a point where he needs to get the proper reps and not just jam a bunch of at-bats down him.”
